Hamad Fasteners, Riyadh, Saudi Arabia, is a well-established manufacturer and supplier of top-quality industrial fasteners such as Hastelloy C22 bolts. With their high corrosion resistance and strength, these bolts have been engineered to perform satisfactorily in extremely aggressive chemical environments. Hamad Fasteners makes sure that all the products are of international standards, catering to the chemical processing, petrochemical, and marine industries. A focus on quality and strength, the company offers Hastelloy C22 bolts with enduring performance for use in applications that require resistance to oxidizing and reducing agents.
The Hastelloy C22 bolts consist predominantly of nickel (56%), chromium (20%), molybdenum (14%), and iron (6%), with minor components of cobalt, manganese, and silicon. This specific composition of alloy has superior resistance against pitting, crevice corrosion, and stress corrosion cracking in reducing and oxidizing conditions. The bolts have high tensile strength, commonly ranging between 690 MPa, and they can withstand mechanical properties across a broad range of temperatures. The superior corrosion resistance of Hastelloy C22 renders the bolts very suitable for applications involving severe chemicals and high temperature.
